RE: Watercad Model with Water Meter and Backflow preventer?
Craig Calvin
Click here for information on the book Advanced Water Distribution Modeling and Management. Also, the following articles may help: How can I model a backflow preventer (PBV)? How can I find the total volume of water through a certain element?

Modeling No Backflow
OSMAR RODRIGUEZ
Can anyone please assist in how to model a backflow preventer for a pipe network in StormCAD? Am looking to model a pipe system where flow will only be occurring in one direction and backflows are prevented by a check valve at the outfall. From what…

Mismatches between "Transients results viewer" and "Profiles". HAMMER V8i
Alberto Cruces
Hello, I am working on the effects of a pump shut down in a quite long pressurized main with HAMMER V8i. My model consists of 3 pumps that deliver 120l/s to a distance of 1800m through a 250mm main. As usual, the main has a very steeped start to exit…

Distribution Sytem Wide Hammer and Transient Analysis of RPZ
bpeskin
I am attempting to set up a model to demonstrate how a RPZ (Reduced Pressure Principle Backflow Preventer) will respond to Hammer. For those unfamiliar with the operation of an RPZ, I have attached a document which outlines this very well. …

Backflow Preventer
mattneppl
Right now I am modeling a backflow preventer using a check valve and a general purpose valve. Is this the best way to model a backflow preventer? I read in the help menu that this is a way to model it. I also noticed that I don't have any headloss…
